Configure connection, authentication, processing, and sync behavior.
Connection
`auto` uses recommended defaults for the selected connection mode.
Default: `gpt-5.1-codex-mini` for Direct API; `claude-4.5-haiku` for Local Claude session.
Switch between provider API credentials and local Claude session auth.
Used by `claude_sidecar` runtime. Example wrapper: `["wrapper", "claude", "--"]`.
Authentication
Use `auto` unless you need a specific token source.
When method is `command`, command stdout is used as the token.
Command format: JSON string array, e.g. `["iap-auth", "--audience", "gateway"]`.
Template variables: `${auth.token}`, `${auth.type}`, `${auth.source}`.
Some values are controlled outside this screen and take priority.
